Aging can take a toll on many of your body’s functions, including your eyesight. If you are over 65, have your eyes examined regularly by an optometrist, especially if you’d like to enjoy sharp vision for the years to come. During your eye exam, your optometrist may put drops in your eyes that widen your pupils so that they can examine the back of your eyes. This is the only way to detect some of these age-related eye problems that have no early signs or symptoms.

Presbyopia

Presbyopia, or age-related long-sightedness, is a slow loss of near vision. It often causes headaches and eyestrain.
